Channel ping timeout expired

Hi,

I get following error in Ema logs. We have ConnectionPingTimeout is set as 30 seconds. Could this be a network issue ? I am using ema3.6.6.L1. My application is a ema consumer.

Thank you for reaching out to us.

According to the error, the API cut the connection due to the ping timeout. This indicates that it didn't recieve anything back from the server during the ping timeout period.

It could be the network issue or the problem in the application or the API.

You can enable the XmlTraceToFile and XmlTracePing configurataions in the channel to verify what the problem is. However, enbling tracing can impact performance of the application.

As it turned out OnLoad without LD_PRELOAD has resolved the issue.
